FASTENER.

Specification of Letters Patent. Patented A 3 11 1916 Application filed Deeember 27, 1915. Serial No. 68,669.

Be it known that I, GEORGE W. HoAR, a

citizen of the United States, residing at Valtham, in the county of Middlesex and State of Massachusetts, have invented new and useful Improvements in Fasteners, of which the following is a specification. This invention relates to improvements in fasteners particularly adapted for fastening carriage curtains and the like. Y

The object of the invention :is to provide an inexpensive and simple fastener adapted to secure the edges of curtains or side pieces of vehicles to the body portion thereof, said fastener having means to prevent said curtain from becoming detached from said body accidentally; but" permitting said curtains to be easilyand 'quickly detached when desired." j

Theinvention consists in the combination and arrangementof parts set forth-in the following specification and particularly pointed out in the claims. H

Referring to the drawings: Figure 1 is a transverse section through the holder of the fastener embodying my invention and illustrating the resilient member arranged in its proper position withrelation to the top of saidholder. Fig. 2 is a detail plan view of the back of the holder of said fastener. Fig.

.3 is a. section taken substantially on the line 33 of Fig. 1 illustrating the stud in its locked position in the holder. Fig. 4, is an enlarged detail section taken substantially on the line 4-4 of Fig. 3. Fig. 5 is a section similar to Fig. 3, illustrating the position of the stud with relation to the holder immediately prior to its being withdrawn from said'holder. Fig. 6 is a section taken on the line 6-6 of Fig. 5. Fig. 7 is a modified form of resilientmember. Fig. 8 is a section taken on the line 8-8 of Fig. 1.

Like numerals refer to like parts throughout the several views of the drawings.

In the drawings, 8 is the holder and preferably embodies in its construction a top 9 formed of sheet metal with a peripheral i1 ange 10 formed integral therewith. A back 11 also formed of sheet metal is arranged substantially parallel with the top and-preferably secured thereto by tongues 12 preferably formed from material constituting said flange 10. The tongues 12,. preferably three in number, are arranged to pro ec t through perforations 13 in said'back and to 'silient member 12.

be bent or' clenched against the outer sur- .face of said back to rigidly secure saidfback in contact with the edge of the flange 10. A reslllent member 14;, preferably constructed of wire, is arranged in circular' form 17 within said casing between the top and back members thereof and along'the inside of the 'flange10Q The end' portions 15 and 16 of the resilient member 14 are bent inwardly with respect to the circular portion 17 of said resilient fastener and arranged substantially side. by side. These end portions 15 and 16 extend substantially across the central portion of said holder with the extremities 18 and 19 thereof ofiset so as to normally engage each other and to ency of the material thereof.

The top 9 and back 11 are each provided w1th an aperture 20, theaperture for said top being substantially in alinement with the aperture for the back and both are arranged substantially central with respect to said members so as to expose the intermediate portions of the end portions 15 and 16 The holder 8 is g of the resilient member. also provided With adepression 21 formed 'be retained'insuch a position by the resilipreferably in the back 11' adjacent'to one v side of the aperture 20 and in alinement with the extremities'18 and 19 of the re-;

Upon the back of the holder at one side of the aperture 20 is'a pair of abutments 22 and 23 preferably formed by depressing the inner face of said back at 21 which abutments are arranged to engage the extremities 18 and 19 respectively when said ex- 24 is inserted in said holder until the groove 26 is opposite the members 15 and 16, permittingsald members tosprmg into sald" groove back to their'contra'eted positions from which they weremoved during the msertion of the head end of said stud. Under ordinary conditions, the end portions 15 and 16 rest against the inner surface 28 of the top 9 of said holder, but should an attempt be made to remove the holder from the stud or to apply'a direct longitudinal pressure to said holder relatively to said stud in the direction of the arrow a, Fig. 3, to withdraw said stud from said holder, the shoulder 27 will engage the members 15 and 16 and depress said members so that the extremities 18 and '19 thereof will be forced against the inclined surfaces 22 and 23 into the depression 21, causing said extremities to be forced firmly together and held while said pressure on said stud is maintained, and thereby more firmly gripping said stud andabsolutely preventing the removal of said holder from said stud.

To insure a free movement of the members 15 and 16 between the top 9 and back 11, spacers '29 and 29' have been provided preferably formed integral with the back by partially detaching a portion of material thereof and bending said material in the direction of the top 9 so as to engage the face 28 thereof. The holder 8 is usually attached to the side curtains of the motor vehicle represented at '30 while the stud 2 1 is attached to the body of the vehicle. WVlien used in this connection, the side of said holder opposite the depression 21 and as indicated by the letter A is disposed toward the edge of the curtain or side'and when it is desired to detach the holder from the stud the side of said holder A is tipped with relation to the stud 24 in the direction indicated by the arrow I), see Fig. During the tipping of said holder, as stated,'the

rim 31 of the head of said stud is adapted to engage the members 15 and. 16' upon the opposite side of the aperture 2O from the:

depression 21 and separate said members so as to permit the head of said stud to pass therebetween.

As the rim 31 engages the members 15 and 16, as stated, the rim 32 of said stud upon the opposite side of the annular groove 26 engages the undersides of said members 15 and 16 adjacent to the depression 21 and has a tendency to force said members upwardly away from said depression and against the inner face 28 of the top 9, thus enabling the rim 31 to readily separate the resilient end portions 15 and 16, moving the extremities 18 and 19 thereof into the positions illustrated in Fig. 6. In Fig. 7 I have illustrated a resilient member 33 having end portions 34 and 35 formed straight instead of offset as in Fig. 1. To accommodate this type of resilient member the inclined surfaces 22 and 23 illustrated in Fig. 4: may be placed at a slightly greater distance apart than shown in said Fig. 1, otherwise the construction is the same. The

spacer 29 is disposed between the members 15 and 16 and has an additional function in that it is formed tapering as illustrated in Fig. 8, so as to properly space the members 15 and 16 during the assembling of the device.

Having thus described my invention what I claim and desire by Letters Patent to secure is:
